Abstract

The invention provides a shape memory polymer stretchable displayer substrate and methods for preparing the same, and relates to a displayer substrate and a method for preparing the same. The invention solves the problems that the conventional displayer substrate has fixed shape and size and cannot be stretched. The displayer substrate of the invention is prepared from a shape memory polymer, a curing agent and a fiber reinforcing material or prepared from the shape memory polymer and the fiber reinforcing material. The method 1 comprises the following steps of: uniformly distributing the mixture on the surface of a mould plate by a suspension rod and performing thermal treatment in a vacuum furnace. The method 2 comprises the following steps of: adding the mixture into the mould, and then performing hot-pressing treatment. The shape memory polymer stretchable displayer substrate can be stretched for deformation and bent, is quite light and thin, and can replace the glass or plastic substrate of the displayer; and the shape memory polymer stretchable displayer substrate can be applied to the displayer capable of being stretched for deformation as well as the displayer of the product which is portable and can be used for information and video signals.

Description

technical field [0001] The invention relates to a display substrate and a preparation method thereof. Background technique [0002] With the rapid development of the communication and computer industry, the computer has become a necessary tool in the work and life. The display as a necessary part of the computer has also changed from a green display, a single display picture tube display, through a flat right-angle display, The development of flat-panel displays to today's liquid crystal displays is based on glass, quartz or plastic materials. When the display substrate is prepared, the shape and size of the display are fixed and cannot be stretched, so that its use is limited. At present, there is no A report on stretchable display substrates. Contents of the invention [0003] The invention aims to solve the problem that the shape and size of the existing display substrate are fixed and cannot be stretched, and provides a shape memory polymer stretchable display substra...
